Contamination of coastal and marine bird species with plastics: Global analysis and synthesis
This review summarizes global data on plastic contamination in coastal and marine bird species across all seven continents, finding that seabirds like fulmars, shearwaters, and albatrosses are the most heavily affected. Birds ingest microplastics, mesoplastics, and macroplastics that can cause death directly through gut blockage and indirectly through toxic chemicals absorbed onto or released from the plastic. Several contaminated species are already classified as endangered.
Plastic pollution threatens shorebirds: a global review
This systematic review summarizes global research on how plastic pollution threatens shorebirds through ingestion and entanglement. The findings highlight that microplastics are spreading throughout coastal ecosystems, and since shorebirds serve as indicators of environmental health, their contamination signals broader risks to the food webs that also affect human communities.
Prevalência e tipos de plásticos em Albatrozes e Petréis (aves: procellariiformes)
Researchers quantified and classified plastic debris in Procellariiformes seabirds — albatrosses and petrels — found on Brazilian beaches, finding plastic ingestion in multiple species. These ocean-going birds are among the most vulnerable to plastic pollution because they feed from the ocean surface where plastics concentrate.
Co-contaminants of microplastics in two seabird species from the Canadian Arctic
This study examined whether Arctic seabirds that ingest microplastics also accumulate chemical contaminants carried by the plastic particles. The findings suggest that microplastics can act as vectors for delivering toxic chemicals to seabirds, adding to the burden of pollutants already present in Arctic food webs.
Impacts of plastic debris on biota and implications for human health: A South African perspective
This review from a South African perspective documents plastic ingestion and entanglement across a wide range of marine species including sharks, fish, turtles, and 36 bird species, with microplastics posing sub-lethal effects and macroplastics causing entanglement deaths. The authors identify the need for better monitoring infrastructure to detect population-level impacts and track human health risks from consuming contaminated seafood.
Birds and plastic pollution: recent advances
This review summarizes how plastic pollution affects birds across both aquatic and terrestrial habitats, covering ingestion, entanglement, and chemical exposure from macro- and microplastics. Researchers found that hundreds of bird species have accumulated plastic in their tissues, with effects ranging from physical injury to hormonal disruption and reproductive harm. The study positions birds as valuable indicator species for monitoring the broader environmental impact of plastic pollution.
Plastic pollution threatens shorebirds: a global review
This systematic review summarizes global research on how plastic pollution threatens shorebirds. While focused on wildlife rather than human health, it highlights the sheer scale of microplastic contamination in coastal environments where both birds and humans interact with the same food web.
From mudflats and saltpans to Open Sea: Plastic ingestion and PBDE/MeO-BDE accumulation in Waterbirds from southern Portugal
Researchers studied plastic ingestion and flame retardant chemical accumulation in breeding waterbirds from a coastal lagoon in southern Portugal. They found microplastics in regurgitated pellets and droppings from multiple species, with gulls and terns ingesting the most particles. The study also detected persistent flame retardant chemicals in eggs, feathers, and preen oil, suggesting that plastic pollution exposes coastal birds to both physical and chemical hazards across their feeding habitats.
Seabirds from the poles: microplastics pollution sentinels
Researchers reviewed four decades of studies on microplastic ingestion by seabirds in Arctic and Antarctic regions, covering at least 13 species. They found that polar seabirds regularly ingest microplastics, with polyethylene being the most common type detected. The study highlights that even some of the most remote ecosystems on Earth are not immune to plastic pollution.
Uso de recursos de origen antrópico por parte de aves marinas que reproducen en la Patagonia argentina
This study synthesized research on how seabirds breeding along the Argentine Patagonian coast use human-derived resources, including discarded fishing bycatch, urban waste, and anthropogenic nesting materials. Researchers found that at least fifteen species rely on such resources for food or nesting, with commercial fishing waste being the most widely used across twelve species. The findings highlight concerns about microplastic and debris ingestion alongside potential benefits, underscoring the complex relationship between marine birds and human activities.
Birds as bioindicators of plastic pollution in terrestrial and freshwater environments: A 30-year review
This 30-year review of 106 studies examines how birds in freshwater and land environments are affected by plastic pollution. Most research has focused on larger plastic pieces, while microplastic exposure in these bird species is understudied and nanoplastic exposure has not been investigated at all. The authors urge researchers to develop standardized methods for measuring small plastic particles in birds, which could serve as valuable warning signs of plastic pollution across ecosystems.
The hidden cost of following currents: Microplastic ingestion in a planktivorous seabird
Researchers documented microplastic ingestion in Mediterranean storm petrels, finding that these planktivorous seabirds ingest microplastics while foraging in pelagic areas where plastic debris accumulates alongside their planktonic prey in ocean currents.
Plastics and waterbirds in Brazil: A review of ingestion, nest materials and entanglement reveals substantial knowledge gaps and opportunities for research.
This review of plastics and waterbirds in Brazil found substantial evidence of plastic ingestion and use of plastics as nest material across many species, but identified major knowledge gaps due to limited studies. The authors call for systematic monitoring and greater research attention on how plastic pollution affects Brazil's rich waterbird diversity across its vast aquatic environments.
Microplastics ingestion and endocrine disrupting chemicals (EDCs) by breeding seabirds in the east tropical Atlantic: Associations with trophic and foraging proxies (δ15N and δ13C)
Scientists studied five species of tropical seabirds and found endocrine-disrupting chemicals in every species tested, including flame retardants, UV filters, and musk fragrances. Birds that ingested more microplastics tended to carry higher levels of certain contaminants, suggesting plastics may act as a delivery mechanism for harmful chemicals. The findings raise concerns about how plastic pollution in the ocean is exposing wildlife to a cocktail of hormone-disrupting substances.
